Black synthetic leather shoulder strap with gold hardware, purchased at Seria. 〈Size〉 Length: 105.5 cm Thickness: 1 mm I attached it to a bag once, but I stopped using it because I was worried it might break due to the weight, given its 1 mm thickness. I've used it once, but I don't think there are any noticeable stains or scratches. This product can be used as a strap for small bags or as a smartphone chain. - Color: Black - Material: Synthetic leather - Hardware Color: Gold - Type: Shoulder strap Thank you for looking.
